Abstract : A coherent, CW, X-band, dual-frequency radar has been used to detect stationary targets in the Chesapeake Bay. It is shown that by multiplying returns at two frequencies and averaging, sea clutter is suppressed. If the decorrelation of the two clutter returns is greater than that of returns from a stationary target, the signal-to-clutter ratio of the two-frequency system is shown to be greater than that of a comparable single-frequency radar.
